Calls to and from England, Scotland, Wales, and those parts of Eire not listed are all national calls. However, calls from numbers beginning 28 or 91 to 01776, and from numbers beginning 20 to 01586, are regional rate.

Note: calls between charge groups in Northern Ireland can be dialled without the 028 prefix, even though they are regional or national rate calls.

028 has been introduced as a replacement all numbers in Northern Ireland. The mapping was:

However, numbers only diallable using the full code changed as follows:

01232 UABBBB became 10UA BBBB

(where U is 0 or 1).

The new numbers were introduced by 1999-06-01 with parallel running until 2000-09-16. Dialling without codes involved a flash change early on 2000-04-22, with 5 or 6 digit dialling used before then and 8 digit dialling afterwards (though only within a charge group until 2000-09-16).
